Abstract: ABSTRACT OF THE DISCLOSURE     A brake pad assembly having self-adjusting character-istics for correcting uneven wear of the frictional surface for use in a vehicular brake having a brake rotor, the assembly comprising a pad of frictional material attached to a rigid backing plate and having a circumferentially symmetrical central friction surface area fox engaging the brake rotor.  The friction surface area has its center of pressure coincident with the surface area centroid, and is unsymmetrically increased should uneven wear occur, thereby displacing the area centroid toward the region of uneven wear and causing an increase in the surface pressure loading over the unaffected region of the frictional sur-face area and a corresponding increase in the wear rate of the unaffected region so as to return the frictional surface area to its original circumferentially symmetrical configuration and re-position the friction surface area centroid to its original coincident relationship with the center of pressure.

Abstract: ABSTRACT      A connector for terminating a flat cable comprises a contact support, a pressure member, and a strain relief.  A metal clip on either end of the connector acts as a latch to maintain the three elements in a single package and to transmit the forces imposed by the strain relief directly to the contact support.  A detent formed on the contact support provides a two-position catch for the latch.  A protuberance formed on the clip bites into the end wall of the pressure member to prevent withdrawal of the clip from a slot formed in the pressure member and to allow displacement of the end wall in response to flexure of the clip.

Abstract: Abstract of the Disclosure Aligned conveyors support and supply a single file of articles to the infeed lug conveyor of a horizontal form, fill and seal wrapping machine.  The aligned conveyors are oriented to intersect the infeed conveyor at an angle which can range from 90 to 135 degrees.  The chosen angle of intersection is dependent upon article size and geometry.    One of the aligned conveyors functions to organize the articles in abutting relation and yet maintains crowding forces or backlog pressure to a minimum.  As the leading article of the row of abutting articles arrives at the intersection of the aligned conveyors and the infeed conveyor, it is controllably propelled to the infeed lug conveyor of the wrapping machine.

Title: Mechanically-operated level control for  dishwashers
Inventor: CRAWFORD JOHN G
IPC: A47L15/42
Filed: 1979-11-30
Granted: 1982-07-06
Abstract: ABSTRACT OF THE DISCLOSURE           A level control arrangement for dishwashers in which the in-flow to the dishwasher tub from the water supply line is automatically terminated when the water level in the tub reaches a predetermined level.  The arrangement includes a two-stage level control valve dis-posed in a valve housing installed downstream of the water fill valve. The valve is moved into and out of engagement with the valve housing in response to a connector which in turn is in operative engagement with a stem of a float positioned in the dishwasher tub. When the water level in the tub approaches a predetermined washing level, the float rises in the tub to a position where the connector permits the valve to move to a sealing position, thereby terminating further flow to the dishwasher tub.  When the water is drained from the tub, the float stem moves the connector thereby releasing the pressure exerted against the sealed valve through a port located within the valve.  Further movement of the float stem and the connector opens the valve, thereby resetting the arrangement for the next fill sequence.

Abstract: ABSTRACT OF THE DISCLOSURE         A water outlet pipe 50 leading to a feed water tank 1 is connected to a separator 20 disposed downstream of an evaporator 15.  A heat exchanger 6 and a first control valve 52 are disposed in the water outlet pipe, the valve being influenced by the level in the separator 20.  In the heat exchanger 6 heat is transmitted, from the water flowing out of the separator, to the feed water flowing to the vapour or steam generator.          Between the heat exchanger 6 and the first control valve 52 a bypass pipe 55 branches from the water outlet pipe 50 and contains a second control valve 56 which is also influenced by the level in the separator 20.  The bypass pipe 55 leads into a condenser 35.  A considerable proportion of the water leaving the separator 20 is discharged via the bypass pipe 55 to the condenser 35 as a result of said pipe 55 branching off upstream of the first control valve 52.  Consequently, the flow cross-section of the first control valve 52 and the cross-section of the safety blow-off device to be provided on the feed-water tank can be consider-ably reduced in size.

Abstract: ABSTRACT OF THE DISCLOSURE            Tablet side arm assembly is provided for mounting on a chair. The assembly includes a side arm positionable at the side of the chair and a floating tablet pivotally connected by pivot means to the side arm on a pivot axis situated with respect to the side arm for displacing the tablet along a rotational movement path sequentially forwardly and outwardly and thence downwardly and backwardly relative to the horizontal from a substan-tially horizontal working position extending crosswise of the side arm to a substantially vertical storage position extending laterally of the side arm, the pivot means including an angle bracket having a mounting portion carrying the floating tablet for pivotal movement therewith and an inclined journal portion rigidly connected to the mounting portion and extending at an acute angle thereto and pivotally connected to the side arm.  Thus, a stable support for mounting a floating tablet, preferably removably, on a chair is provided, which is simple, rigid and durable in construction, com-paratively inexpensive to fabricate and assemble, attractive in appearance, and relatively easy to use.  Moreover, the construction may be conveniently produced from readily available components and materials, using a minimum of manufacturing steps and by way of conventional equipment and tooling. Clearly, the construction requires a bare minimum of necessary parts, yet the same coact in a manner ensuring long-lasting and essentially trouble free operation.  The parts remain sufficiently out of the way of the user in terms of the rotational movement path contemplated for ease in changing the tablet from working to storage position and the pivotal connection con-templated ensures that the tablet when in working position is completely stable and free from play.

Abstract: RCA 73,145A      ABSTRACT OF THE DISCLOSURE In a tuning system for generating a tuning voltage for tuning a television receiver, channel identification apparatus includes a memory for storing binary signals repre-senting boundary voltages having magnitudes corresponding to magnitudes of the tuning voltage between tuning voltage ranges for respective adjacent channels within a band. Because the tuning voltage characteristics associated with conventional television receivers include separated portions corresponding to respective frequency bands in which the television channels are located, boundary voltages corre-sponding to the boundaries of the tuning voltage ranges of the highest and lowest frequency channels in each band are also stored.  As the memory locations are addressed, the boundary voltages are compared to the tuning voltages. Control apparatus causes the memory location associated with the next boundary voltage to be addressed and causes channel number apparatus to generate binary signals repre-senting the next channel number when the magnitude of a predetermined one of the boundary voltage associated with an addressed one of the memory locations and the tuning voltage exceeds the magnitude of the other one.  Display apparatus displays the channel number represented by the binary signals generated by the channel number means.  Because the boundary voltages are utilized, the channel identification apparatus, as disclosed, is particularly well suited for use in a signal seeking system.

Abstract: ABSTRACT OF THE DISCLOSURE A novel one-way valve, preferably a substitute mitral heart valve, is provided herein.  The mitral heart valve comprises a stent including a circular base and a pair of upstanding,diametrically opposed struts, separating a pair of diametrically opposed,arcuately shaped, depressed re-liefs, each such relief being bounded by a smooth curve interconnecting the struts to the circular base.  A flexible, durable, biocompatible covering is secured to the stent and provides two equal,opposed,molded flexible,flappably-movable,valve leaflets secured along the smooth curve defining the upper perimeter of the reliefs.  The valve leaflets each are preformed and molded so that the free margin of the biocompatible leaf-lets along the free edges of each of the leaflets between the tips of each associated strut is so related to the circumference of the circular base that, when the valve is in its open position, the cross-sectional area of the exit is substantially equal to the cross-sectional area of the inside of the circular base.  When the valve is in its relaxed and natural closed position, the shape of the leaflets is such that the free edges of the leaflets drop down and sealingly meet in substantially wrinkle-free form at a curve of apposition in the plane defined by the tips of the struts and the axis of the valve and follow the approximate shape of a catenary curve.
